臨夏Low Phase Noise Reference Source-96040A-美國FLUKE
Simplify your RF calibration system
The Fluke
Calibration 96040A RF Reference Source enables you to simplify your RF
calibration system by replacing many of the instruments and accessories that
make up your current system. Its precision signal level and attenuation, high
signal purity and precision low distortion modulation make this reference
source superior to the general-purpose signal generators that are often used to
calibrate spectrum analyzers, modulation meters, RF sensors, attenuators, and
similar instruments. Its low phase noise provides superior phase noise
performance.
Unlike many RF
calibration solutions, the 96040A is designed specifically for RF calibration,
with a calibration-oriented user interface that makes it easy to learn and use.
The 96040A speeds up calibration procedures, reduces opportunities for operator
errors, and greatly simplifies RF metrology. As the core of an RF and microwave
calibration system, the 96040A covers the majority of test points required for
calibrating spectrum analyzers of any frequency range.
Automated with
MET/CAL® Plus Calibration Management Software, the 96040A reduces complexity
and calibration times, dramatically improving efficiency and increasing
capacity by 50 % or more over manual methods.

Broad, versatile workload coverage
The 96040A
calibrates a broad workload of RF calibration devices, including:
• Spectrum
analyzers
• Modulation
meters and analyzers
• RF power meters
and sensors
• Frequency
counters
• Attenuators
• And more
The metrology
associated with calibrating these items becomes simpler because you have fewer
error sources and uncertainty contributions to consider.
More than just an RF calibrator
There are many
applications in research and development, manufacturing test, and ATE needing
better performance than a general purpose signal generator. If wide frequency
coverage, frequency resolution, low harmonics, phase noise and spurious
content, signal level and attenuation accuracy, or dynamic range are critical
parameters the 96040A is an ideal solution.
Cut the cost of your RF calibration system in half
As the central
instrument in a high capability RF spectrum analyzer calibration system, the
96040A can cut your costs in half. The 96040A replaces all of these parts of a
“typical” RF calibration system:
Up to four signal
sources (from audio/ function generators to RF signal and low phase noise
sources)
·
Power meters and power sensors
·
Step attenuators
·
Filters
·
Pads
·
Couplers
·
50 MHz frequency counter
The 96040A not
only reduces the initial need to purchase, install and configure RF system
components, but it also reduces the maintenance and calibration costs
associated with all of that equipment. The 96040A is also easier to transport
than a heavy rack of equipment and accessories, making it a good solution for
on-site calibration.
With its 4 GHz
frequency range, the 96040A performs more than 80 % of all the tests required
on high performance, high frequency spectrum analyzers.
For workload items
that require frequencies beyond 4 GHz, you can use an RF and microwave source
that you probably already own alongside the 96040A to address the few remaining
higher frequency test points. For many spectrum analyzer models operating below
4 GHz, you only need a 96040A to perform the entire calibration. You can’t
simplify much more than that!
No need for additional function generators
The 9640A
Reference Source’s internal modulation capability makes it suitable for
applications that require precision modulation to be applied to the output
signal, such as modulation analyzer calibration and spectrum analyzer sweep
time testing using an AM signal with more accurate modulation rates. You don’t
need additional function generators as a low frequency modulation source—the
96040A delivers it all.
Designed for RF calibration
The 96040A user
interface is designed to simplify processes for calibrating typical items in
your workload, such as spectrum analyzers, RF level meters and receivers.
Parameter offset, stepping, relative and UUT/DUT error readout modes allow you
to work accurately and efficiently, following familiar calibration procedures.
You’ll find it easier than ever to determine the performance and tolerances of
units under test.
The 96040A front
panel is equipped with dedicated function keys, context-sensitive softkeys, and
a bright, easy-to-read color display that make it easy to learn and operate.
You can set output levels in terms of power (watts or dBm), voltage (RMS or
peak to peak) using familiar multipliers and exponent forms. You can move
easily between voltage, power and dBm units without losing entered values or
accuracy. In error readout mode to adjust the reading, simply rotate the spin
wheel and the UUT error is displayed directly in dB, ppm or percent.
The simple,
calibration-oriented user interface also makes troubleshooting easier if you
encounter an unexpected result or an out-of-tolerance condition while following
a manual or automated calibration procedure.
“What you set is what you get” accuracy and signal purity
A rugged, precise
levelling head delivers 96040A signal levels directly to the unit under test
(UUT) input just the way you set them on the front panel. This unique “What you
set is what you get” feature helps you avoid problems like losses, noise,
interference, and mismatch errors, which can be caused by using intermediate
connectors and cables. This approach also maintains the integrity of low-level
signals. The head maintains signal precision and noise immunity throughout a
154 dB dynamic range, down to the very lowest levels at -130 dBm.
The leveling head
reduces lead changes from 25 to just 5 during a typical calibration, allowing
you to “connect once and test many,” extending unattended times in an automated
system, and reducing connector wear.
Calibrated as a system to assure system performance
The 96040A is
supplied with a 50 ohm leveling head. The /75 model has both 50 ohm and 75 ohm
leveling heads. Each mainframe and head are calibrated together as a complete
system. System calibration helps assure overall system performance. Each 96040A
instrument is supplied with a comprehensive ISO 17025 compliant certificate of
calibration with data for all key parameters, including level and attenuation,
output VSWR, and phase noise. You can be assured that your 96040A is traceable,
plus RF metrology and uncertainty analysis become much simpler and faster.
Accredited certification is available for the 96040A and both 50 ohm and 75 ohm
heads.
State-of-the-art phase noise performance
With reduced low
phase noise optimized for low and high offset frequencies and specifications
from 1 Hz to 10 MHz offsets, the 96040A offers exceptional phase noise
performance beyond that required for today’s high performance workloads.
Phase noise data
is included in the 96040A certificate of calibration. Instead of relying only
on the more conservative guaranteed specifications, users have actual
performance data for their unit. Even with the best low phase noise signal
generators, filters are commonly used during spectrum analyzer phase noise
calibration tests, reducing noise levels at wide (high) offset frequencies to
improve test margins. The 9600FLT 1 GHz bandpass filter accessory is designed
specifically for high performance spectrum analyzer wide-offset phase noise
testing and connects easily to 96040A models in either benchtop or rack-mounted
applications.
Selectable frequency reference input/ output expands functionality
Selectable
external frequency reference input is available as a standard feature on the
rear panel of the 96040A. The input allows you to lock the frequency output to
an external reference, such as the Fluke Calibration 910R Rubidium Standard,
for applications where high clock accuracy or use of a common reference
frequency is important. The frequency reference output allows a UUT to be
frequency locked to the 96040A internal reference clock. This configuration is
often required to reduce frequency offset errors that may occur between the
reference source and the UUT.
Simplify frequency response tests with 96040A sweep functions
RF applications
often require a frequency sweep. The 96040A’s sweep functions simplify the
application of manual legacy spectrum analyzer frequency response testing, as
well as filter response measurements.
Automate with MET/CAL® software for “walk-away” efficiency
In a typical
automated RF calibration process, the operator must frequently intervene to
change test setups, thus limiting the benefits that can be realized by the
automation. Walk-away automation can increase calibration system capacity by up
to 25 percent using procedures you develop in MET/CAL Plus Calibration
Management Software. For example, the manufacturer’s calibration procedure for
calibrating the Agilent E4407B 26.5 GHz spectrum analyzer requires 27 different
and complex test setups. On the other hand, the 96040A, used with MET/CAL Plus
Calibration Management Software, can perform the major core of required tests
with a single setup. Only six additional setups would be needed using a MET/CAL
procedure.
MET/CAL procedures
created by Fluke Calibration for the 9640A models can be used by the 96040A in
9640A emulation mode. Optimized automated procedures can save time for the
operators by allowing them to leave the system running while attending to other
work. For example, the E4407B MET/CAL procedure for the legacy 9640A, running
in emulation mode on the 96040A, allows for a total 90 minutes of “walkaway”
time within the total two-hour calibration runtime.
Using the 96040A with other automation solutions
The 96040A is also
integrated easily into existing automated systems and software. The time
savings and efficiency gains offered by the 96040A can be realized by
structuring test sequences to take full advantage of its “connect once measure
many” capabilities.
The 96040A is
designed to match or exceed the performance and functionality of the HP3335A
and HP8662/3A in calibration systems. With HP3335A and HP8662/3A GPIB command
emulation as standard, replacing these popular but obsolete and
difficult-to-maintain products becomes just a plug-and-play substitution.
